| 面对这场突如其来的暴雪，只要我们巧加应对，及时加固大棚和清扫积雪，减轻大棚的压力，棚塌的现象也可以避免。 In the face of this sudden blizzard, as long as we skillfully cope with it, we should strengthen the greenhouse and clean up the snow in time, and reduce the pressure of the greenhouse. The phenomenon of shed collapse can also be avoided. 雪自然滑落法 Snow natural slide method 有条件的可以在草苫上加盖一层棚膜，如没有就将草苫卷起，置于大棚后坡，当积雪厚达8厘米左右时就会在光滑的棚膜上自动滑下。8米宽的大棚可自动滑下2/3。棚的坡度越大，自动滑下的越多，这样可以有效缓解积雪对大棚的压力。 Conditions can be in on the grass mat with a layer of films, such as not the grass with rolled up in a greenhouse slope, when the snow thickness of 8 cm will slide down on a smooth film on. The 8 meter wide shed can automatically slide down 2/3. The greater the slope of the shed, the more automatic slide down, which can effectively alleviate the pressure of snow on the greenhouse. 人工扫雪法 Artificial snow removal method 日光温室和单拱棚，因不能上人，清雪只能人工清理！取一根长约5米的竹竿(可根据大棚宽度加长竹竿长度)和一块长1米，宽20厘米的木板订成一个刮板，当积雪达到5～7厘米厚时，站在大棚的后坡，将雪轻轻一推，积雪就会顺着光滑的棚膜滑落，在操作过程中应避免损坏棚膜。 Sunlight greenhouse and single arch shed, because can not go to people, snow cleaning can only be cleaned manually! Take a piece of bamboo about 5 meters (according to the width and length of bamboo shed lengthened) a 1 meters long, 20 cm wide wood set into a scraper, when the snow reached 5~7 centimeters thick, after the slope stand in the greenhouse, the snow gently push the snow will follow the smooth slide film during operation, avoid damaging the film. 烧火加温法 A heating method 雪大了来不及除时，在大棚里面烧木炭或生两堆火，但是要注意安全，适当通风后再进入大棚，防止一氧化碳中毒。 When the snow is too big for time, we will burn charcoal or produce two fires in the greenhouse, but we should pay attention to safety, and then enter the greenhouse after proper ventilation, so as to prevent carbon monoxide poisoning. |
